I've gradually moved over to Mastodon for most of my posting. The pocket of Fedi I reside within (queer fedi) is quite nice.
Last year, I seriously started using Bluesky. It's okay, but a little too much like "old Twitter" for my tastes. I still use it, but my most interesting posts go on Fedi.
This is all to say, Bluesky has replaced Twitter for me, but I was already phasing it out.
